Patient discussion about arm

Q. I have a constant pain in the inside part of my arm. What can it be? In the last few weeks I have noticed that I have a right arm pain. The strange thing is that the pain is in a specific point in the inside part of the arm, very near to the elbow. I thnk the pain started for the first time during a baseball game but I am not sure.
I work in a factory and as I sad before I use my right arm for baseball, and this pain hinders me.
What can it be?

A. I myself play a lot as a pitcher, and i have the same pain. It is more painful when the forearm is flexed towards the body. I went to my GP about it because it drove me nuts, and he said that I need to take anti-inflammatory drugs, and if it will not work he will inject me something. he prescribed me a great medication and I didn't need the injection.

Q. I developed an AV Fistula after a heart catherization procedure. I am bleeding through the tissues in left arm I am on coumadin, but currently have a lower than usual INR. Corrective surgery was scheduled for yesterday, but had to be delayed. I am concerned that I have a large amount of blood (dark red) bleeding though the tissues right under the skin in my left arm. Should I seek immediate medical attention? The bleeding is over approximately a 3 and 1/2" area on my left arm. Came about in a period of a few minutes.

A. well, you are on blood thinners. i wouldn't take the chance. i mean- i'm not sure i follow what is happening over there. it could be a severe problem or nothing. i would let a doctor check it out. the worse thing that could happen is you wasting a day at the hospital, on the other end of that scenario- you can end up dead. i would go with the first one.

Q. My son displays behavior such as hooting, screeching, flapping arms, "chicken" dancing, rocking... Hi members, please help me to choose the right way. My son displays behavior such as hooting, screeching, flapping arms, "chicken" dancing, rocking, bouncing, jumping, limited repetitive play skills, low self esteem, difficulty commencing and occasionally sustaining adult directed tasks, difficulty maintaining relationships with adults and peers, he becomes easily frustrated and will become physically and verbally aggressive, can overreact to being touched, easily distracted by noise, short attention span, likes routine and finds it difficult to change task, difficulty listening, and difficulty following verbal instructions. He is like this at home and school. I have been told by the local NHS group that he is not autistic because of his parent’s separation and divorce in his early life and he does not present these behaviors as a "pervasive feature". Instead they suggest he needs a hearing check and he has "neuro developmental immaturities". What is your opinion? Should I get a second opinion?

A. if you ask me - they could be right. anyway i would be careful from over-the-net-diagnosis. their specialist saw the child and examined his behavior, he probably know what he is doing. and even if you are not sure- get a second opinion. can't hurt can it?
